There are several illnesses/syndromes that are often found that accompany CRPS.  I will briefly describe them.  For a more detailed look into these associated illnesses, you can purchase my book CRPS and Allphabet Soup available at Amazon.  https://a.co/d/dF6Vu6q

Dysautonomia- Dysautonomia is a disorder that disrupts your autonomic nervous system.  The autonomic nervous system controls your blood pressure, heart rate, starting of movement, digestion, sexual arousal and breathing .  You will see how this comes into play when we discuss how CRPS effects the body as a whole and causes associated syndromes.
